l Application filed October 21, 1916. Serial No. 126,956.

To all whom t may concern:

Be it known that WALTER F. SANDnnsoN, a citizen of the United States, residing at Bristol, in the county oi' Bucks and State of Pennsylvania, have invented certain new and useful Improvements in Nonlteillable Bottles, of which the following is a specification.

This application relates to certain Anew and useful improvements in non-refillable bottles. c

The primary object of the invention resides in the provision of a non reiillable bottle which will be of simple and inexpensive construction as well as highly efficient in use.

Another object of the invention resides in the provision of a bottle of the above stated character which will be formed in such manner as to prevent contact of the liquid or luid with any metallic parts thereof` while the bottle is being relieved of its contents.

A further object of the invention resides in the provision of an inner stopper' composed of cork or some other suitable yielding material, spaced 'from the ball or spherical valve and resting upon a curved shoulder provided for the same, and an outer stopper automatically locked in position within the end of the bottle neck and in engagement with the inner stopper, said outer stopper having an outer or discharge passage registering with a similar outlet or discharge passage extended through the inner stopper, the outlet end of the iirst mentioned outlet or discharge passage being iiared to term a pouring lip.

A still further obj ect of the invention resides in the provision of a non-reillable bottle of the above stated character which will be provided with an air inlet or vent passage and composed of the minimum number of parts constructed insuch manner that the inner stopper may be placed in any position upon the shoulder, and extensive alterations in the construction of the conventional form of bottle, now in general use will be unnecessary.

With these and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

1n the accompanying drawings forming a part Vof this application and in whichlike designating characters refer to correspond ing parts throughout the several views,

Figure 1 is a longitudinal section through my improved non-reillable bottle with all ot' the parts in normal position.

Fig. 2 is a plan view of the same.

Fig. 3 is a transverse sectional view on the plane of line 3-3 of Fig. 1, looking in the direction indicated by the arrows, and

Fig. 4 is a detail transverse section on the plane of line 4**4 ot Fig. 1, looking in the direction indicated by the arrows.

Referring more in detail to the drawings, 1 designates a bottle neck of conventional form, which has a valve seat 2 formed therein by reducing the interior diameter thereof, a suitable distance from the end of the neck, as clearly shown in Fig. 1 of the drawings. The ball cr spherical valve 3 normally rests upon the valve seat 2. rlhe circular shoul- Vder 4 is also formed in the interior of the bottle neck 1 and beyond the valve seat 2 by increasing the interior diameter of the outer portion of the valve neck. rihe circular shoulder 4 is provided in its outer face with an annular groove 4 the purpose of which will presently appear.

A bottle neck is also provided with a circular or annular groove 5 in the outer portion thereof, adjacent the extreme outer or discharge end of said bottle neck. rlfhe purpose of this groove as well as the shoulder 4 and groove 4 will presently be. fully stated.

The inner yieldable or cushioning stopper 6 is composed of cork or some other suitable material and may be placed upon the shoulder 4 in any position desired, as communication between the air vent passage 14 and the air vent passage 15 is formed by the groove 4', regardless ot' the position or the relative positions of said passages 14 and 15.

This inner stopper 6 has a transverse outlet or discharge opening 7 which `.should register with the outlet or discharge opening 8 of the outer stopper 9, which latter outlet or discharge opening 8 has a `flared outer end l0, providing a pouring lip or flange 11.,- whereby theI contents of the bottle may be properly directedto a drinking glass or other vessel.

The outer stopper 9 may be formed ot glass or the like and is preferably provided with the lip or flange 11 extending around its outer edge and of irregular outline, as

clearly shown in Fig. 2 of the drawings, said lip or. flange 11 extending over the end of the bottle neck and protecting the saine as well as the outer end of the stopper 9.

, In the portion of the stopper 9 opposite the portion through which the outlet or discharge passage 8 is formed, an air inlet passage or vent 12 is provided and has a turned outer end 13 extending through the flange 11 and opening upon the under face of the same. The air inlet passage or vent 12 will register with the air inlet passage or vent 14C of the inner stopper 6 when the outer stopper 9 is placed in proper position upon said inner stopper 6, with the outlet or discharge passage 8 registering with the outlet or discharge passa-ge 7. This will make itV possible for air to enter the turned end 13 of the air passage or vent12, pass through the latter and through the air passage or vent 14; to the groove il then, through the air inlet passage orv vent 15 in the bottle neck 1 and to the main passage of said bottle neck to replace the liquid leaving the bottleV when the-latter is properly tilted,

`thereby assuring a steady and even liow of the liquid from the bottle.

In order to lock the Stoppers 6 and 9 in .proper position within the bottle neck and thereby prevent tampering with the valve 3 by a party attempting to refill the bottle, l provide a pair of locking boltsl@ positioned in a transverse bolt passage 17 in the outer stopper 9 and normally pressed outwardly by means of an expansion spring 18 positioned therebetween, as clearly shown in Fig. d of the drawings. 1t will be seen that Vthe heads of the saine rest in 'the enlarged outer ends of the passage 17. As soon as the stopper 9 is forced inwardly a sufficient distance to bring the spring locking bolts 16 to position opposite the groove 5 however, the spring 18 will force the bolts 16`into the groove 5, thereby automatically locking the stopper 9 in position and preventing removal of the same without destruction of theV stopper 9 or the bottle neck 1 and it will be evident that the Vbottle neck 1 should give way before any `great amount of damage is done to the stopper 9. By positioning the locking bolts 16Y in the central portion of the stopper 9 between the passages 8 and 12, it will be impossible for any iuids passing through the passages 7 and 8 t0 come into contact with either locking bolts 9 or the spring 18, the only metallic parts of the device.

While the form of the invention shown and described is what is believed to be the preferred embodiment thereof, it is neven theless to be understood that minor changes therein may be made in the details of construction and arrangement of parts without departing from the spirit or scope of the invention.

lVhat I claim as new is:

1. A. non-reillable bottle including a bottle neck provided with an interior enlargement forming a valve chamber and a shoulder above said chamber, said enlargement being provided with an air vent extending longitudinally thereof and with an endless groove extending around the upper face of said shoulder and communicating with said vent, a valve movable in said chamber, super-imposed Stoppers supported on said shoulder above said valve, said stoppers being provided with registering fluid outlets communicating with said valve chamber and with registering air vents communicating with the groove provided in said shoulder, and means for locking the outer stopper to said bottle neck.

2. A non-refillable bottle including a bot- Ytle neck provided with an interior enlarge* ment, said enlargement having an air vent extending longitudinally thereof and being shaped to provide a valve chamber and a shoulder positioned above said chamber, said shoulder having a groove extending around the .upper face thereof and communicating with said vent, a valve disposed in said chamber, a stopper supported on said shoulder above said valve, a second stopper supported on said first stopper and provided at its upper end with an outwardly directed flange spaced from the upper end of said bottle neck, said Stoppers being provided with registering fiuid outlets communicating with said valve chamber, and with registering air vents communicating with said groove, the air vent in the outer stopper being extended through said iange and opening into the underface thereof, and means for locking` the outer stopper to the bottle neck.

in testimony whereof I ailix my signature in presence of two witnesses.
